THE POSITIVE AND NEGATIVE EFFECTS OF TECHNOLOGY IN THE LIFE OF CHILDREN

Technology has helped to increase the mentality of our children in many aspects; academically, mentally, physically etc. It has changed the way they relate and communicate with their peers, relatives and others around them.

During the time of old children were not used to modern facilities but in these modern era children are conversant with almost all the electronic gadgets they are allowed to work with. Sometimes, children even teach their parents how to make use of some electronic gadgets and how to access so sites on the internet.

NEGATIVE EFFECT OF TECHNOLOGY ON OUR CHILDREN

Because of technology, many children spend most of their times playing video games, watching television and using other gadgets at their disposal without considering the facts that they have school works or other house chores to do. 

Children who are addicted to browsing the internet have the possibility of being exposed to many hazardous contents such as drug use, unprotected sex, constant intake of alcohol, smoking, and bullying which might lure them into engaging in some nasty behavior that will end up endangering their future both physically, mentally or otherwise. In these modern days, there are many sites created specifically for adult; when children access these sites, they try to practice what they see on it, believing that it is good for them since they got it from the internet.

In situation where Children spend more time on the internet, playing video games, watching television, etc, they find it really difficult to socialize or spend time with their age mates because they have seen the technologies they are exposed to as their friend and companion, sometimes, they find it difficult to leave these gadgets and welcome their Parents when they get back to the House.

THE PARTS OF THE COMPUTER SYSTEM AND THEIR USES

Before I start discussing the parts of the computer I will like to define computer in my own understanding.

Computer is an electronic device that is capable of accepting data, stores information as a soft copy based on instruction or users command.

This device has different parts which includes the following:

·     Monitor

·     Mouse

·     Keyboard

·     C.P.U (Central processing unit)

·     Speaker

·     Printer

·    Monitor: It can also be referred to as the computer screen. It is the part of the computer system that displays all the command or information given to the computer as instructed by the user.

·     Mouse: This is a basic part of the computer that helps the user to communicate and instruct the computer on the choice he/she make.

·     Keyboard: This play the same role as the mass but the only thing that differentiates these two components of the computer is that the keyboard is use to input keys or words into the computer but the mouse is use to point and click and select items you want to work with.

·     C.P.U: This is the part I refer to as the brain of a computer in the sense that it has the able to store and interpret every information it’s receive from other parts of the computer. the c.p.u is made of different parts such as the processor, motherboard, CD Rom, optical drive etc.

·  Speaker: I call it a sound magnifier because it helps to magnify or increase the sounds that take place in the computer system by outputting the sound.

·  Printer: This component is used to produce soft copy of information in the system therefore converting it to a hard copy (which means that you can feel or touch it).

FOB (FAECAL OCCULT BLOOD) TEST OR STOOL ANALYSIS

The FOB (Faecal Occult Blood) Test helps to diagnose bleeding disorders of the intestine (gut).

What is FOB (Faecial Occult Blood) test? This is a type of test that detects small amount of blood in the faeces of an individual which may not be known to you without proper diagnosis. Feaces are also referred to as stool analysis). In the other hand, the test can also be called the stool analysis.

What is feaces or stool? This is waste that you excrete from your anus. Occult means invisible).

What is the main purpose/reason of conducting this test?

FOB (Faecial Occult blood) Test is conducted because there are many disorders or illness which may cause bleeding into the intestine (gut) such as bowel polyps, duodenal or gastric ulcers bowel (colorectal) cancer. e.t.c. In this process, your faeces or stool becomes bloody or black

 in colour due to the high rate of bleeding. Although sometimes, these disorders only bleed with a drop of blood, in this case your faeces will look normal. Without your knowledge that it contain small amount of blood.

Nevertheless, the FOB or Stool Analysis test can be conducted to detect either small or large amount of blood in your faeces. The test may be done if you have symptoms like constant pain in you abdomen. It may also be conducted to monitor bowel cancer before any symptoms increase.

Attention: It will be good to know that the FOB (Faecal Occult Blood) test will only detect that you are bleeding from somewhere but cannot give notice of the part bleeding.

How can one conduct faecal occult blood (FOB) test?

To conduct the test the person whose Faeces or stool is to be examined will be given a sterilized universal container in which the Faeces or stool will be put after which it must have been produced and will also be advised by laboratory scientist or Doctor to avoid the intake of certain types of food for 3 days before producing the faeces or stool for the diagnosis (although is optional).

A sample of the Faeces (Stool) will be collected and placed into an FOB (Faecal Occult Blood) buffer which already have a chemical in a liquid form then cover to check or stir without covering make sure that the Faeces(Stool) is properly mixed.

Open an FOB (Faecal Occult Blood) strip and deep it into the FOB Buffer and allow for about 30 minutes then take you result.

NOTICE: if two red lines appears clearly on the FOB (Faecal Occult Blood) strip it is said to be positive which means that there is bleeding in your intestine (gut) but if only one red line appear clearly on the same strip it is said to be Negative which means that there is no trace of bleeding in your intestine (gut).

BEST PHYSICISTS

James Clerk Maxwell
In contrast to Newton and Einstein, Edinburgh-born Maxwell (1831-79) is virtually unknown to the general public. Yet his contribution to physics was every bit as significant, particularly his discovery of the theoryof electromagnetism. This showed that electricity, magnetism and light are all manifestations of the same phenomenon, the electromagnetic field. The development of radio, TV and radar were the direct consequences. Maxwell also carried out pioneering work in optics and colour vision. However, in his later years, his God-fearing Scottish upbringing brought him into dispute with the evolutionary thinking of Darwin and others and he wrote papers denouncing natural selection.

Michael Faraday
Largely self-educated, Faraday (1791-1867) became one of the greatest scientists of his day thanks to the patronage of the eminent English chemist Humphry Davy, who hired him as an assistant in 1813. Faraday went on to establish the idea of the electromagnetic field and discovered electromagnetic induction and the laws of electrolysis. His electromagnetic devices formed the foundation of electric motor technology. He twice rejected offers of a knighthood and when asked to advise on chemical weapons for the Crimean war effort, refused on ethical grounds. Einstein kept a picture of Faraday on his study wall (alongside pictures of Newton and Maxwell).

Marie Curie
The first woman to win a Nobel and the first person to win two separate Nobels, Curie (1867-1934) was born in Poland and won her first Nobel in 1903 with husband, Pierre, for discovering radioactivity. However, she was not allowed to participate in the keynote lecture winners give because she was a woman. After Pierre died in a road accident in 1906, she won her second Nobel in 1911 for discovering radium, though an attempt was made to rescind it when news emerged of her affair with married colleague Paul Langevin. After collecting the prize, Curie was pilloried                                                            by the French press. Langevin was ignored.

                                                                  Richard Feynman

One of the 20th century’s most influential and colourful physicists, Feynman (1918-88) played a key role in the development of quantum electrodynamics, the theory that describes how light and matter interact, earning him a Nobel prize in 1965. Feynman also contributed to the fields of quantum computing and nanotechnology and was a member of the Rogers Commission that lambasted Nasa over the destruction of space shuttle Challenger in 1986. He was a keen drummer, experimented with drugs and often worked on physics problems in topless bars because he said they helped him concentrate. Feynman died in 1988, aged 69.

Ernest Rutherford

New Zealand-born Rutherford (1871-1937) is considered one of the greatest of all experimental physicists. He discovered the idea of radioactive half-life and showed that radioactivity involved the transmutation of one chemical element to another. He was awarded a Nobel in 1908 “for his investigations into the disintegration of the elements”. Rutherford later became director of the Cavendish Laboratory at Cambridge University where, under his leadership, the neutron was discovered by James Chadwick in 1932 and the first experiment to split the nucleus was carried out by John Cockcroft and Ernest Walton. The element rutherfordium was named after him in 1997.

           Paul Dirac

   One of the most revered – and strangest – figures in physics. The son of a Swiss father and English mother, Dirac (1902-84) was born in Bristol. He predicted the existence of antimatter, created some of quantum mechanics’ key equations and laid the foundations for today’s micro-electronics industry. Dirac won a Nobel in 1933 but remained “an Edwardian geek”, according to biographer Graham Farmelo. He turned down a knighthood because he didn’t want people using his first name, while his daughter, Monica, never once remembered him laughing. “This balancing on the dizzying path between genius and madness is awful,” Einstein said of him.
